Under California law, Gov. Jerry Brown will decide whether to uphold the parole or reject it.

The Orange County District Attorney's Office is hoping Brown denies Han parole, the Orange County Register reports, claiming she has not addressed her mental health issues and is still a risk to the public.

Jeen Han may be released from prison after serving nearly two decades for plotting to kill her identical twin sister.

Deputy District Attorney Nikki Chambers said in a letter to Brown that Han is manipulative and has received letters from several men offering her money, a job and a place to stay if she's released. One man in England reportedly sent Han $100,000.

"This manipulative ability is not surprising, given her extreme intelligence coupled with an untreated personality disorder," Chambers wrote. "The fact remains that she is still flexing the manipulation muscles that she used when she recruited two young men to murder her sister."
